Ok here is my question. I currently have 20 dialup lines and 5 ISdn
dialup line. am a fairly small ISP butI am growing at an alarming rate.
Currenty I use a PM 2e/30 with a 5bri Card. As you can see I am out of
ports. I am thinking about going T1 not only to keep up with the
"Possible" technology of 56k since it only works if there is one
conversion in the line. Here are my questions.

What is the difference between channelized t1 and regular T1.

Which is better?

Does the PM3 support both?

What is a rough estimate of a a T1 with 24 dialin numbers from
bellsouth? Channelized or not whichever apply?

Can either T1 do ISDN? So the customer calls one phone number and gets
either ISDN or Analog when dialing in?

Does the PM3 do ISDN on the 24 channels without any modem cards. In
other words the modem card are only if you are going to support analog
calls.

conecerning the PM3 Do you have to provision the t1 so that lets say 8
are for analog and 16 are for ISDN, so if 8 analog users are on and
another call will it get a ninth channel that is not used or do you have
to specify which are anolog and which are digital.

I would appreciate a little light on the subject.
